Our story began over 50 years ago. Over the decades, we have received
hundreds of awards for our products and satisfied hundreds of thousands
of people who take their entertainment seriously - like you!
Rotel was founded by a family whose passionate interest in music led them
to manufacture high-fidelity components of uncompromising quality. Through
the years, that passion has remained undiminished and the family goal of
providing exceptional value for audiophiles and music lovers, regardless
of their budget, is shared by all Rotel employees.
RotelÊs engineers work as a close team, listening to, and fine tuning, each
new product until it reaches their exacting musical standards. They are
free to choose components from around the world in order to make that
product the best they can. You are likely to find capacitors from the United
Kingdom and Germany, semiconductors from Japan or the United States,
while toroidal power transformers are manufactured in RotelÊs own factory.
We all have concerns about our environment. And, as more and more
electronics are produced and later discarded, it is especially important for
a manufacturer to do all it can to engineer products that have a minimum
negative impact on landfill sites and water tables.
At Rotel, we are proud to do our part. We have reduced the lead content
in our electronics by using special ROHS solder, while our new Class D
(not digital) amplifiers are up to five times more efficient than our legacy
designs and still deliver power and performance. These products run cool,
give minimum wasted energy, are good for the environment and give better
sound too.
Finally, we have printed this manual on recycled paper stock.
While we understand that these are small first steps, they are still important
ones. And we continue to pursue new methods and materials for a cleaner
and greener manufacturing process.
All of us at Rotel thank you for buying this product. We are sure it will bring
you many years of enjoyment.
Getting Started
Thank you for purchasing the Rotel RC-1570 Stereo Control Amplifier. When
used in a high-quality music audio system, your Rotel product will provide
years of musical enjoyment.
The RC-1570 is a full featured, high performance component. All aspects
of the design have been optimized to retain the full dynamic range and
subtle nuances of your music. The RC-1570 has a highly regulated power
supply incorporating a Rotel custom-designed toroidal power transformer
and custom-made slit foil capacitors. This low impedance power supply has
ample power reserves, which enables the RC-1570 to easily reproduce the
most demanding audio signals. This type of design is more expensive to
manufacture, but it is better for the music.
The printed circuit boards (PCB) are designed with Symmetrical Circuit Traces.
This insures that the precise timing of the music is maintained and faithfully
recreated. The RC-1570 circuitry uses metal film resistors and polystyrene
or polypropylene capacitors in important signal paths. All aspects of this
design have been examined to ensure the most faithful music reproduction.
RC-1570 Stereo Control Amplifier
10
The main functions of the RC-1570 are easy to install and use. If you have
experience with other stereo systems, you shouldnÊt find anything perplexing.
Simply plug in the associated components and enjoy.
A Few Precautions
WARNING: To avoid potential damage to your system, turn off ALL
the components in the system when connecting or disconnecting the
loudspeakers or any associated components. Do not turn the system
components back on until you are sure all the connections are correct
and secure. Pay particular attention to the speaker wires. There must
be no loose strands that could contact the other speaker wires, or the
chassis of the amplifier.
Please read this manual carefully. In addition to basic installation and
operating instructions, it provides valuable information on various RC-1570
system configurations as well as general information that will help you get
optimum performance from your system. Please contact your authorized
Rotel dealer for answers to any questions you might have. In addition, all
of us at Rotel welcome your questions and comments.
Save the RC-1570 shipping carton and all enclosed packing material for
future use. Shipping or moving the RC-1570 in anything other than the
original packing material may result in severe damage to your amplifier.
Fill out and send in the ownerÊs registration card packed with the RC-1570.
Also be sure to keep the original sales receipt. It is your best record of the
date of purchase, which you will need in the event warranty service is
ever required.
Placement
Like all audio components that handle low-level signals, the RC-1570 can
be affected by its environment. Avoid placing the RC-1570 on top of other
components. Also avoid routing audio signal cables near power cords. This
will minimize the chance it will pick up hum or interference.
We recommend installing the RC-1570 in furniture designed to house audio
components. Such furniture is designed to reduce or suppress vibration which
can adversely affect sound quality. Ask your authorized Rotel dealer for advice
about component furniture and proper installation of audio components.
The RC-1570 is supplied with an RR-AX92 remote control and must be
placed where the infrared signal from the remote can reach the front panel
Remote Sensor.
Cables
Be sure to keep the power cords, digital signal cables and regular audio
signal cables in your installation away from each other. This will minimize
the chance of the regular audio signal cables picking up noise or interference
from the power cords or digital cables. Using only high quality, shielded
cables will also help to prevent noise or interference from degrading the
sound quality of your system. If you have any questions see your authorized
Rotel dealer for advice about the best cable to use with your system.
The RR-AX92 Remote Control
Some functions can be done with either the front panel controls, or the
supplied RR-AX92 remote control. When these operations are described,
the square call out numbers refer to the main unit, while the encircled letters
refer to the remote control.
NOTE: The remote control can be used to operate the basic functions
of Rotel tuners and CD players. Remote control keys labeled GHMN
can be used to operate CD or Tuner functions in your system. For the
remote to operate properly, make sure both the remote and the CD
or Tuner are both in same remote code. For more information please
contact your authorized Rotel dealer.
Remote Control Batteries
Two UM-4/AAA size batteries (supplied) must be installed before the remote
control can be used. To install the batteries, remove the cover on the back of
the RR-AX92. Install the batteries as shown in the illustration in the battery
well. Test the control for proper operation, then replace the cover. When
the batteries become weak the remote control wonÊt operate the RC-1570
consistently. Installing fresh batteries should eliminate the problem.
AC Power and Control
AC Power Input u
Your RC-1570 is configured at the factory for the proper AC line voltage in
the country where you purchased it (either 120 volts AC or 230 volts AC
with a line frequency of either 50 Hz or 60 Hz). The AC line configuration
is noted on a decal on the back panel.
NOTE: Should you move your unit to another country, it may be possible
to reconfigure it for use on a different line voltage. Do not attempt to
perform this conversion yourself. Opening the enclosure of the unit
exposes you to dangerous voltages. Consult a qualified service person
or the Rotel factory service department for information.
NOTE: Some products are intended for sale in more than one country
and as such are supplied with more than one AC cord. Please only use
the one appropriate for your country/region.
The RC-1570 should be plugged directly into a 2-pin polarized wall outlet.
Do not use an extension cord. A heavy duty multi-tap power outlet strip may
be used if it (and the wall outlet) is rated to handle the current demanded
by the RC-1570 and all the other components connected to it.
If you are going to be away from home for an extended period of time
such as a month long vacation, it is a sensible precaution to unplug the RC1570 (as well as other audio and video components) while you are away.
POWER Switch and Power Indicator 1

Troubleshooting
Cannot Connect via Bluetooth
Most difficulties in audio systems are the result of incorrect connections,
or improper control settings. If you encounter problems, isolate the area
of the difficulty, check the control settings, determine the cause of the fault
and make the necessary changes. If you are unable to get sound from the
RC-1570, refer to the suggestions for the following conditions:
If you cannot pair your Bluetooth enabled device to the RC-1570, delete the
memory of the previous connection on the RC-1570 and on your device.
On your device this is often listed as "Forget this Device". On the RC-1570
IR remote PRESS and HOLD the STOP M button for 5 seconds until the front
display shown „Reset BT DB List?„ then release the button. Select <Yes> and
press „ENT„. Then try to make the connection again.
Power Indicator Is Not Illuminated
The Power Indicator ring around the power button and the basic items in the
Display window should be illuminated whenever the RC-1570 is plugged
into the wall power outlet and the POWER switch is pushed in. If it does not
light, test the power outlet with another electrical device, such as a lamp.
Be sure the power outlet being used is not controlled by a switch that has
been turned off.
Fuse Replacement
If another electrical device works when plugged into the power outlet, but
the Power Indicator still will not light when the RC-1570 is plugged into
the wall outlet, it indicates that the internal power fuse may have blown.
If you believe this has happened, contact your authorized Rotel dealer to
get the fuse replaced.
No Sound
Check the signal source to see if it is functioning properly. Make sure the
cables from the signal source to the RC-1570 inputs are connected properly.
Check all the wiring between the RC-1570 and the power amplifier, and
the speakers.
